<< For simplicity's sake, let's assume that we have a phase comparator that needs a 1 Hz difference between its two inputs before it creates a DC correction signal large enough to control the VCO (no
Hi Andre' that is not my appreciation of how off air standards work. You do not try to get a lock up in 64 microseconds (one frame). In this case the PLL is not trying to compensate for poor short t

<< Allow me to quote from the book "Phase Locked Loops, Principle and Practice", McGraw Hill 1996, by P.V. Brennan University College, London. Page 22: "...As far as the control loop is concerned, it
There does not have to be a frequency error at all for a phase comparator to output a correction voltage...only for the oscillator being stabilized to have a _tendency_ to drift away from the desire
